Research on the Design of Anti-static Shielding Devices for Electrical Equipment

This study focuses on the development and application of nanostructured metal films in electrostatic discharge (ESD) protection devices for electrical equipment. By depositing zinc, aluminum, and silver nano-functional films onto polypropylene non-woven fabrics via high-vacuum magnetron sputtering, the research systematically evaluates their electrical performance and morphological characteristics. Key results indicate that silver films exhibit superior conductivity, achieving a volume resistivity of on 1.5 mm XLPE substrates with a breakdown field strength of 28.5 kV/mm. COMSOL Multiphysics simulations validate a 27% reduction in insulation layer electric field strength when using silver films, confirming their effectiveness in mitigating ESD risks. The proposed composite materials are applied to high-voltage cable shielding layers and intelligent power distribution cabinet monitoring systems, reducing ESD-related failures by 76%. A lightweight, flexible sensor array integrated with edge computing and IoT technology enables real-time electrostatic monitoring with an 8 ms response time and long-term stability (2.3% signal attenuation over 100 cycles). This work provides a technical framework for next-generation anti-static shielding devices in critical electrical infrastructure, including power distribution networks, electronics manufacturing, and high-voltage systems, addressing the challenges of miniaturization and operational reliability in modern engineering.
